I think it's AND relation. It should be smth. like this:
 [SoC,][IP family,] "ti,davinci_mdio"
where "ti,davinci_mdio" is mandatory always
 [IP family] - mandatory for IP/SOC family and can be "ti,keystone_mdio" or "ti,cpsw-mdio" (last one is added by subsequent patch)
 [SoC] - mandatory for SoC. now can be "ti,am4372-mdio"

I can update it as below:
- compatible		: Should be "ti,davinci_mdio"  
			  and "ti,keystone_mdio" for Keystone 2 SoCs
 			  and "ti,am4372-mdio" for am472x SoC
and in subsequent patch
			 and "ti,cpsw-mdio" for am335x, am472x, am57xx/dra7, dm814x SoCs
			 and "ti,am4372-mdio" for am472x SoC
